T 0 all whom it may concern Be it known that we, HENRY DE SMITH andDENNIS CHURCH, citizens of the United States, and residents ofRochester, in the county of Monroe and State of New York, have inventedcertain new and useful Improvements in BoX-Form-Attaching Means forBoXCovering Machines, of which the following is a specification.

This invention relates to box-covering machines and has particularreference to'the means for securing the box-form in detachableconnection with the rotary carrier-spindle forming part of suchmachines.

In the use of box-covering machines, boxforms of various shapes andsizes are usually employed according to the shape and size of the boxesto be covered, and it is therefore desirable that a simple and effectivemeans be provided by which these various boxforms may be quickly andconveniently attached to and detached from the rotary carrier-spindle ofthe box-covering machine.

To provide such a means has been the obj ect of our invention.

In carrying the invention into effect we combine with thecarrier-spindle a plurality of opposing clamping jaws one'or more ofwhich is carried by an adjustable part, and means for adjusting one ormore of said jaws to cause them to cooperate in clamping a box-form inoperative connection with the carrier-spindle.

Referring now to the accompanying drawings forming part of thisspecification,-Fig ure 1 represents one end of the rotary carrierspindleof a box-covering machine provided with a box-form attaching meansembodying our invention, and also showing said attaching means inoperative clamping engagement with a box-form, a part only of whichlatter is shown. Fig. 2 is a View of the same looking from either thetop or bottom as shown in Fig. 1. Fig. 3 is a view similar to Fig. 1showing a modified form of the invention.

Similar reference characters designate like parts in the several figuresof the drawmgs.

In the particular embodiment of our invention shown in Figs. 1 and 2,the rotary carrier-spindle, indicated at 2, is provided at its front endwith a collar 3 having at opposite sides thereof two pairs of ears H,

44, between and to which are pivotally connected two levers 5, 5. Theselevers, which are pivoted as described at a point intermediate theirends, are arranged longitudinally of the carrier-spindle with theirforward ends projecting beyond the adjacent end of the carrier-spindleto provide opposing jaws for engaging and clamping therebetween asuitable cooperating part of a box-form. In the present case, the saidproecting ends of the levers 5, 5, are provided with pivoted jaws 6, 6,which are self-adjusting to conform to the shape of the cooperating partof the box-form, which in the present case is shown as a dove-tailedprojection 7 this form of projection being desirable in that theclamping action of the opposing jaws on its angular surfaces operates todraw and hold the form in close and firm contact with the end of thecarrierspindle or with the enlarged flanged face of the collar 3thereon.

As a means for operating the levers 5, 5, to move and hold theirclamping jaws in operative clamping engagement with the box-form, wehave located a cone 8 on the carrier-spindle for longitudinal adjustmentthereon whereby it may be moved into engagement with the adjacent rearends of the levers 5, 5, and rock said levers on their pivots in amanner to move the clamping aws at the forward ends of the levers in adirection toward each other and into operative clamping engagement withthe cooperating art of the box-form as shown. In order to' detach thebox-form from connection with the carrier-spindle it is only necessaryto move the adjusting cone in the proper direction to release the leversfrom their clamping position.

The cone 8 may be adapted for adjustment on the carrier-spindle by anysuitable means, the same in the present case having a screwthreadedconnection with a sleeve 9 on said carrier-spindle for longitudinaladjustment thereon and being adapted to be secured in adjusted positionby means ofv a jam nut 10. In the present case the said cone 8 and jamnut 10 are each shown as being provided with a series of peripheralteeth or rojections 11 for the engagement therewit of a spanner or othersuitable operating wrench, by means of which the adjustment of saidparts may be facilitated.

Referring now to Fig. 3 of the drawing, we have shown therein anotherembodiment of our invention, which differs from that shown in Figs. 1and 2 in that one of the clamping jaws (the lower one as shown in thedrawing) is carried by a fixed arm 12 of the collar 3 instead of by anadjustable one. In such case the operation of the device in effectingclamping engagement with a box-form is consequently accomplished by theadjustment of but one aw, the adjustably supported one, as shown. It isthus seen that the jaws 6 both in the preferred and modlfied structuresare contracted to approach one another and clamp against the.oppositesides of the dove-tailed projection 7' whether one or both ofthe jaws (3 are moved inward relatively to the spindle 2.

While we have shown and described differ ent embodiments of ourinvention, we do not wish to be understood as confining ourselves to thedetails of construction which we have disclosed, for it 'is obvious thatconsiderable latitude within the skill of a mechanioian may beindulgedin without departing from the principles of our invention, and as allrier-spindle for engaging the rear or opposite ends of the levers tomove and secure the levers in operative clamping position.

2. Box-form attaching means for box-covering machines, comprising acarrier-spindle having a threaded portion, a collar mounted on saidspindle having projecting ears, a plurality of levers pivotallyconnected at a point intermediate their ends to said ears and having attheir front ends pivoted clamping jaws, an adjusting cone threaded ontosaid screw-threaded portion of the carrier-spindle for engaging the rearor opposite ends of the levers to move and secure the levers inoperative clamping position, and a jamnut for engaging the cone tosecure it in adjusted position.

3. Boxform attaching means for boxcovering machines, comprising acarrier-spindle having a screw-threaded portion, a clamping meanspivotally connected to said spindle and extending longitudinally thereofand adapted for engagement at its front end with a box-form, anadjusting cone threaded on said screw-threaded portion of the spindleand engaging the rear end of said clamping means to bind the front endthereof against the box-form, and a am-nut threaded on the threadedportion of the spindle rearwardly of the cone to hold the latter againstsaid clamping means.
